The lamp device comprises a first part comprising a first light source comprising an LED. In one or more exemplary lamp devices, the first light source comprises an LED panel. An LED panel may be seen as a panel comprising a plurality of LED diodes connected in series and/or in parallel. The LED panel may comprise at least 5 LED diodes, at least 10 LED diodes, at least 20 LED diodes, at least 30 LED diodes, at least 40 LED diodes, or at least 50 LED diodes. In one or more example lamp devices, the first light source comprises an LED panel comprising a first set of LEDs mounted on a first circuit board. The first light source, such as the LED panel, may be configured to emit visible light and/or non-visible light spectrum. The first light source, such as the LED panel, may be configured to emit light according to a photopic response lambda function (e.g. the CIE photopic luminosity function), according to the optical radiation for IPRGC-influenced responses to light (such as described in CIE S026:/E:2018), and/or according to the alpha-OPIC EDI responses. For example, the first light source, such as the LED panel, may be configured to emit light such that the user of the lamp device is exposed to light in the range of 500 lux to 1000 lux. For example, the first light source, such as the LED panel, may be configured to emit light having a color rendering in the range of 80 to 99 color rendering index, CRL For example, the first light source, such as the LED panel, may be configured to emit light having a glare in the range of maximum 19 to 20 unified glared rating, UGR. For example, the first light source, such as the LED panel, may be configured to emit light having a colors temperature in the range of OOK to 8000K. For example, the first light source, such as the LED panel, may be configured to emit light according to one or more of the following MDEI baselines: 1 MDEI, 10MDEI, 250MDEI, 1000MDEI, 1800MDEI, and 2000MDEI.

The output of the first light source may be measured via a light sensor (such as imitating a retinal photoreceptor). The output of the first light source may be controlled (such as weighted and/or adjusted) based on the measured output of the first light source.

An LED of the lamp device may comprise one or more of: a conventional LED (e.g. standard CIE illuminant SPD and/or CIE illuminant series LED), an RGB-W LED, an RGB- WW LED, a full spectrum LED, an O-LED, and a TRI-R LED.

In one or more exemplary lamp devices, the first light source comprises at least one LED. The at least one LED may for example comprise one organic light emitting diode, OLED.

The first light source may be configured to emit visible light e.g. having a wavelength in the range of 380 nm to 780 nm. The first light source, such as the LED panel, may have an optical power output, i.e. configured to emit light with a power, in the range from 1 W to 200 W or in the range from 2 W to 50W. The first light source, such as the LED panel, may comprise one or more sets of LEDs, such as a first set of LEDs and/or a second set of LEDs. The first light source, such as the first set of LEDs and/or the second set of LEDs, may be controlled independently. For example, the first set of LEDs may form an upper part of the LED panel and the second set of LEDs may form a lower part of the LED panel. The first light source may be configured to be controlled in parts, such as the first set of LEDs and/or the second set of LEDs may be configured to be controlled in parts. The first light source may be arranged at a first primary surface of the first part. The first direction may be parallel to a normal of the first primary surface. The first light source may be configured to be arranged substantially perpendicularly to the support surface, e.g. a normal of the first primary surface may be substantially perpendicular to a normal of the support surface.

The first light source is configured to emit light in a first direction. The first direction may be seen as a first main direction, where the light intensity of the light emitted by the first light source is the largest. The first direction may be seen as a user facing direction, such as the first light source emitting light mainly in a direction of a user of the lamp device. The first direction may be in direction of the proximal side. The first light source may provide direct light exposure facing a face and/or the eyes of the user. The first light source may thereby provide the user with a direct light exposure, e.g. based on the need of light exposure of the user. This may for example be advantageous when the user is lacking light exposure when using the lamp device, and is in need of a direct light source such as the first light source. For example, when the lamp device is used as a desktop lamp, the user may work in an indoor environment with a computer display and the first light source may provide a direct light source which may compensate for the lack of light exposure of the user, e.g. during working hours or in wintertime where less natural light is present. An advantage of the first light source may be that the first light source may be used as a conference light, e.g. when the user is performing an online video conversation. By using the first light source as a conference light, the face of the user may appear more clearly for the counterpart by having an improved light exposure of a face of the user using the lamp device. The controller may thereby be configured to control the first light source for use as a conference light. In other words, the controller may be configured to determine a first light configuration being a first conference light configuration.

In one or more exemplary lamp devices, the lamp device may be used as a light therapy lamp. For example, the lamp device may be used to reduce and/or mitigate the impact of jetlag on a user, to improve a circadian cycle of a user, to improve acute alertness of a user, and/or to improve the sleep of a user. Light therapy applications for the lamp device may for example comprise dawn simulation.

In one or more exemplary lamp devices, the first part is attached to the support part. In one or more exemplary lamp devices, the first part is fixedly attached to the support part.

In one or more exemplary lamp devices, the support part comprises a layer of low friction material (such as a slip material) on a surface of the support part configured to be in contact with the support surface. The layer of low friction material may allow the lamp device to be moved, such as turned, rotated, and/or translated on the support surface in an easier manner by sliding the lamp device without having to lift up the lamp device from the support surface. The low friction material may for example comprise felt.

In one or more exemplary lamp devices, the first part and/or the intermediate part is pivotably attached to the support part. In other words, the lamp device may be configured to rotate and/or pivot around an axis of the first part. For example, the first part may be configured to rotate and/or pivot around a longitudinal axis and/or a radial axis of the first part. The lamp device may comprise a joint between the support part and the first part, allowing the first part to rotate/pivot with respect to the support part. By having a joint, the lamp device may be turned, rotated, pivoted, and/or titled in 3 dimensions. The user of the lamp device may thereby adjust the orientation of the lamp device, such as the orientation of a light source of the lamp device with respect to himself. In one or more exemplary lamp devices, the support part may comprise at least two parts which can rotate with respect to each other. For example, the support part may include a first support part being configured to be in contact with the support surface, and a second support part being arranged on the first support part and pivotably/rotatably attached to the first support part. The first support part and the second support part may be concentric, such that the second support part may rotate around the first support part.

The second light source, such as the at least one LED, may have an optical power output, i.e. configured to emit light with a power, in the range from 0.5 W to 100 W or in the range from 1 W to 50W. The second light source may be seen as a directional light source. In other words, the at least one LED may comprise a directional LED. The second light source may be arranged at a second primary surface of the second part. The second direction may be parallel to a normal of the second primary surface. The second light source may be configured to be arranged substantially parallel to the support surface, e.g. a normal of the second primary surface may be substantially parallel to a normal of the support surface.

In one or more exemplary lamp devices, the second part is attached to the first part. In one or more exemplary lamp devices, the second light source is configured to emit light in a second direction. The second direction may be seen as a second main direction, where the light intensity of the light emitted by the second light source is the largest. The second direction may be seen as a support facing direction, such as the second light source emitting light mainly in a direction of a support surface of the lamp device. In one or more exemplary lamp devices, the second light source is configured to face the support surface of the lamp device when the lamp device is positioned on the support surface. In other words, the second light source is configured to emit light from a second primary surface facing the support surface. The second light source may be seen as a task light configured to focus the light emitted onto a task of the user. The second light source may be configured to direct the light emitted in direction of the support surface, e.g. in direction of an area of interest of a user. The area of interest of a user may be an area of a table, a desk, and/or a bed in front of the user of the lamp device.

In one or more exemplary lamp devices, the first part forms an angle, such as a first angle a_1 (alpha_1), with the second part in the range of 60° to 120° and the second direction forms an angle, such as the first angle a_1 , with the first direction in the range of 60° to 120°. The first angle a_1 may for example be in the range of 80° to 100°, such as 85°, 90°, or 95°. In other words, the lamp device may comprise a bend between the first part and the second part. In other words, the second main direction and the first main direction may form an angle in the range of 60° to 120°. The first angle a_1 may be seen as an angle between a normal of the first primary surface of the first part and a normal of a second primary surface of the second part. By having an angle in the range of 60° to 120° between the first part and the second part, the first light source may emit light facing a user of the lamp device (such as user facing direction), while the second light source may emit light facing the support surface (support surface facing direction). The first part and the second part may form at least partly a first housing part of the housing of the lamp device. For example, the first part and the second part may at least partly comprise the first housing part of the lamp device. The first housing part may comprise a first piece of aluminum, where the first piece of aluminum comprises a bend forming an angle in the range of 60° to 120°. The first part may be located on one side of the bend and the second part on the other side of the bend. In other words, the. first part may be located on a first primary housing part of the first housing part and the second part may be located on a first secondary part of the first housing part. The first part, such as the first primary housing part, may comprise a first cavity to accommodate the first light source, e.g. to accommodate the LED panel. The second part, such as the first secondary housing part, may comprise a second cavity to accommodate the second light source, e.g. to accommodate the at least one LED.

In one or more exemplary lamp devices, the first part comprises a third part comprising a third light source. The third light source is configured to emit light in a third direction. The third direction may be in direction of the distal side. In other words, the third light source may be configured to emit light mainly on the distal side. The third light source is configured to face in an opposite direction than the first light source. In other words, the third direction may form an angle, such as a third angle a_3 with the first direction in the range of 100° to 180°. The third angle a_3 may be seen as an angle between a normal of a third primary surface of the third part and a normal of the first primary surface of the first part. The third direction may be opposite to the first direction. The third part may be seen as a part on the back side of the first part, such as a first tertiary surface of the first part. The third light source may be a light source similar to the first light source. The third light source may for example comprise an LED panel. The description related to the first light source may also apply to the third light source. The third direction may be seen as a third main direction, where the light intensity of the light emitted by the third light source is the largest. The third direction may be seen as an indirect light direction, i.e. facing away from the user, such as the third light source emitting light mainly in a direction opposite to a user of the lamp device. The third light source may thereby provide an indirect background light for the user of the lamp device. This may for example be advantageous when the user already has been exposed to enough light when using the lamp device and does not need a direct light source such as the first light source. For example, when the lamp device is used as a desktop lamp, the user may work with a computer display and the third light source may provide an indirect light source providing eye comfort when reading/working on the computer display. The light emitted by the third light source may be reflected by a surface positioned behind the lamp device, such as a surface facing the third light source, e.g. a wall or a separation wall. The third light source may be arranged at a first secondary surface of the first part. The first secondary surface may face in an opposite direction than the first primary surface. The third direction may be parallel to a normal of the first secondary surface.

The first diffuser may be configured to diffuse the light emitted by the first light source along the first part. The first diffuser may provide a diffused light to the user of the lamp device and avoid that the user gets blinded by the light emitted from the first light source. The first diffuser may for example comprise an acrylic cover. The first diffuser may be configured to cover the first part and/or an intermediate part of the lamp device. A diffuser as disclosed herein may comprise one or more of: glass material, acrylic material, thermoplastic material, solid polycarbonate, and light-diffusing plastic.

The first diffuser may provide a first beam angle for the first light source and a second beam angle for the second light source. The first diffuser may provide a first beam angle a_1 larger than 30°, such as in the range from 45° to 360°. The first beam angle a_1 may be in the range from 45° to 180°. The first beam angle a_1 may be in the range from 60° to 120°. The first diffuser may comprise an optical lens for focusing the light emitted by the second light source. The optical lens may be configured to adapt the beam angle of the second light source. The first diffuser, such as an optical lens, may provide a second beam angle a_2 smaller than 100°, such as in the range from 10° to 100°. The second beam angle a_2 may be in the range from 20° to 60°. The second beam angle a_2 may be in the range from 10° to 20°.

In one or more exemplary lamp devices, the first diffuser comprises a first primary part covering the first part and a first secondary part covering at least partially the second part, wherein the first secondary part comprises an opening aligned with the second light source.

The first light data may comprise light measured from an artificial light source and/or a natural light source. The electronic device may be configured to measure, such as via the light sensor, the light emitted from an artificial light source and/or a natural light source. For example, the electronic device may be configured to measure light exposure from a computer monitor at a desk, natural light exposure from a window (such as when the user is sitting at a desk), and/or light exposure from other artificial light sources (e.g. in an office). The controller may be configured to control the first light source, the second light source, and/or the third light source, based on the first light data, such as based on the light exposure measured by the electronic device and/or a light sensor of the lamp device. In other words, the controller may be configured to compensate the controlling of a light source based on the first light data, such as based on the light exposure measured by the electronic device and/or a light sensor of the lamp device.

In one or more exemplary lamp devices, the controller is comprised in the support part. By having the controller arranged in the support part, the controller may be arranged away from the heat generated by the light sources of the lamp device.

Light data, such as the first light data, may be seen as data indicative of a light intake measured and/or obtained by the electronic device. Light data, such as the first light data, may be seen as data indicative of light that the user of the lamp device has been exposed to and/or a user associated with the electronic device has been exposed to. The first light data may be seen as the amount of light (such as light intake) that the electronic device has measured during the last 5 minutes, the last hour, the last day, the last week, the last month, the last year, and/or the last season. The first light data may comprise light measured from an artificial light source and/or a natural light source. The first light data may be data measured by a light sensor of the electronic device. The light data, such as first light data, may be used to determine a lighting need of a user. For example, the lighting need of a user may depend on age, chronotype, behavior, environment, physical state, acute alertness, and/or mental state of the user.

The first light data may comprise light data measured over a time interval, e.g. comprising one or more activities and/or exposition to light of the electronic device and/or user. For example, the user may e.g. have spent an entire day or time interval that was measured on, outside under natural light exposition or inside under artificial light. The first light data may comprise substantially all or part of the measured light, such as light intake, such as several properties relating to the light the electronic device was exposed to. This may be light intensity over time, wavelength, lumens, irradiance vs wavelength, photopic sensitivity, melanopic sensitivity (such as alpha-opic-EDI), timing of the light, light vs dark ratio etc. The first light data may be based on positioning data, weather data, and/or light sensor data obtained by the electronic device. The first light data may comprise and/or be based on behavioral data (such as behavioral patterns) of a user. For example, the electronic device may determine first light data based on a position of the user during a time interval and correlate the positioning data with weather data for the measured positions during the time interval. For example, the electronic device may determine first light data based on a combination of positioning data, weather data, and/or light sensor data. The first light data may be indicative of a light exposure of the electronic device and/or user in one or more environments, such as outside, inside, and/or partially inside/outside. The first light data may comprise full light spectral power distribution, SPD, input measured over a period of time. For example, the first light data may comprise light data weighted using the CIE lambda curve and/or the alpha-opic-EDL

The first light data may be converted to light intake data of the user based on the measured light exposure of the electronic device. The first light data may be indicative of a total amount of recommended light exposure minus a total amount of actual light exposure, i.e. the amount of light exposure that the user lacks or misses.

The lamp device may be configured to control, such as by using the controller, the first light source and/or the second light source based on the first light data.

To control the first light source and/or the second light source based on the light data, such as the first light data and/or the second light data, may comprise to turn on, turn off, control/adjust an on time/off time, control/adjust a light intensity, control/adjust a light temperature, control/adjust a voltage, control/adjust a wavelength, compensate for obtained light data (such as measured light exposure and/or light history of a user), and/or control/adjust a color of one or more light sources of the lamp device, such as of the first light source, the second light source, and/or the third light source.

In one or more exemplary lamp devices, the controller is configured to determine a first light configuration for the first light source based on the first light data and/or the second light data, and the first light source is configured to emit light according to the first light configuration. In other words, to determine the first light configuration may comprise to determine and/or output a first light configuration signal, e.g. to the first light source, based on the first light configuration. In other words, to control the first light source based on the first light data may comprise to control the first light source according to the first light configuration.

A light configuration, such as the first light configuration, the second light configuration, and/or the third light configuration, may comprise one or more parameters such as one or more of: a turn on parameter, a turn off parameter, an on time/off time parameter, a light intensity parameter, a light temperature parameter, a voltage parameter, a wavelength parameter, and/or a color parameter of one or more light sources of the lamp device, such as of the first light source, the second light source, and/or the third light source. The light data, such as the first light data, may be compared to user specific light goals in order to determine a light configuration. A light configuration may be based on one or more light goals of a user. For example, a light configuration may be based on one or more of: the age of the user, photoreceptural weighting, chronotype of the user, alertness level, sleepiness level, time above threshold, time below threshold, mean light timing (MLIT), a light history of the user, seasonality, non-photopic zeitgebers, and daylight availability.

In one or more exemplary lamp devices, the controller is configured to determine a second light configuration for the second light source based on the first light data and/or the second light data, the second light source is configured to emit light according to the second light configuration. In other words, to determine the second light configuration may comprise to determine and/or output a second light configuration signal based on the second light configuration. In other words, to control the second light source based on the second light data may comprise to control the second light source according to the second light configuration.

In one or more exemplary lamp devices, the controller is configured to determine a third light configuration for a third light source based on the first light data and/or the second light data, the third light source is configured to emit light according to the third light configuration. In other words, to determine the third light configuration may comprise to determine and/or output a third light configuration signal based on the third light configuration. In other words, to control the third light source based on the third light data may comprise to control the third light source according to the third light configuration.

A light configuration, such as the first light configuration, the second light configuration, and/or the third light configuration, may comprise one or more parameters such as one or more of: a turn on parameter, a turn off parameter, an on time/off time parameter, a light intensity parameter, a light temperature parameter, a voltage parameter, a wavelength parameter, and/or a color parameter of one or more light sources of the lamp device, such as of the first light source, the second light source, and/or the third light source. A light source may be configured to operate according to a light configuration, e.g. the first light source may be configured to operate according to the first light configuration, the second light source may be configured to operate according to the second light configuration, and/or the third light source may be configured to operate according to the third light configuration. A first light configuration may for example be based on the age of the user of the lamp device. For example, for a user of around 50 years old the recommended light level on the eye in MDEI during daytime should be above or equal to 600 lux. In other words, to control the first light source, the second light source, and/or the third light source based on the first light data, may comprise to control one or more parameters of the first light source, the second light source, and/or the third light source based on the first light data. The one or more parameters of the first light source, the second light source, and/or the third light source based on the first light data may comprise one or more of: a turn on parameter, a turn off parameter, an on time/off time parameter, a light intensity parameter, a light temperature parameter, a voltage parameter, a wavelength parameter, and/or a color parameter.

For example, in a situation where the user of the lamp device is attending a videoconference at his desk, the first light configuration may comprise to set the luminance level of the first light source to 80% and with a color temperature of the light emitted by the first light source to at least 3000 K, such as 4000 K, 5000K, and with a CRI of at least 90.

A first light configuration may be based on a recommended light level on the eye of a user according to the melanopic daylight equivalent illuminance, MDEI. In other words, the first light source may be controlled based on a recommended light level on the eye of a user according to the melanopic daylight equivalent illuminance, MDEI. For example, a recommended light level on the eye for a user of less than 30 years old may be MDEI above or equal to 500 lux during daytime (e.g. from 7am-7pm). For example, a recommended light level on the eye for a user of less than 30 years old may be MDEI less than or equal to 10 lux during the evening (e.g. from 7pm-11 pm). For example, a recommended light level on the eye for a user of less than 30 years old may be MDEI less than or equal to 1 lux during nighttime (e.g. from 11pm-7am).

For example, a recommended light level on the eye for a user of approximately 50 years old may be MDEI above or equal to 600 lux during daytime (e.g. from 7am-7pm). For example, a recommended light level on the eye for a user of approximately 50 years old may be MDEI less than or equal to 10 lux during the evening (e.g. from 7pm-11pm). For example, a recommended light level on the eye for a user of approximately 50 years old may be MDEI less than or equal to 2 lux during nighttime (e.g. from 11pm-7am). For example, a recommended light level on the eye for a user of more than 75 years old may be MDEI above or equal to 700 lux during daytime (e.g. from 7am-7pm). For example, a recommended light level on the eye for a user of more than 75 years old may be MDEI less than or equal to 15 lux during the evening (e.g. from 7pm-11 pm). For example, a recommended light level on the eye for a user of more than 75 years old may be MDEI less than or equal to 5 lux during nighttime (e.g. from 11pm-7am).

A second light configuration may comprise to set the luminance level of the second light source to 100% for a reading task. A second light configuration may be based on a recommended horizontal light level. In other words, the second light source may be controlled based on a recommended horizontal light level. For example, a recommended horizontal light level for a user of less than 30 years old may be at least 1000 lux during daytime (e.g. from 7am-7pm). For example, a recommended horizontal light level for a user of less than 30 years old may be less than or equal to 100 lux during the evening (e.g. from 7pm-11 pm). For example, a recommended horizontal light level for a user of less than 30 years old may be less than or equal to 10 lux during nighttime (e.g. from 11pm-7am).

For example, a recommended horizontal light level for a user of approximately 50 years old may be at least 1200 lux during daytime (e.g. from 7am-7pm). For example, a recommended horizontal light level for a user of approximately 50 years old may be less than or equal to 120 lux during the evening (e.g. from 7pm-11pm). For example, a recommended horizontal light level for a user of approximately 50 years old may be less than or equal to 10 lux during nighttime (e.g. from 11 pm-7am).

For example, a recommended horizontal light level for a user of more than 75 years old may be at least 1500 lux during daytime (e.g. from 7am-7pm). For example, a recommended horizontal light level for a user of more than 75 years old may be less than or equal to 150 lux during the evening (e.g. from 7pm-11pm). For example, a recommended horizontal light level for a user of more than 75 years old may be less than or equal to 15 lux during nighttime (e.g. from 11 pm-7am). The output of the first light source and/or the second light source may be measured via a light sensor. The first light configuration and/or the second light configuration may be determined (such as adapted and/or adjusted) based on the measured output of the first light source and/or the second light source. Light data, such as the first light data, may comprise light intake data from a natural light source only, from an artificial light source only, or for a combination of light sources, depending e.g. on the time interval that is measured for and/or the activities and exposition of the user. The user may e.g. have spent an entire day or time interval that was measured on, outside under natural light exposition or inside under artificial light. The light data may comprise substantially all or part of the measured light intake, such as several properties relating to the light the measuring device was exposed to. This may be light intensity over time, wavelength, lumens, irradiance vs wavelength, photopic sensitivity, melanopic sensitivity, timing of the light, light vs dark ratio etc.

Light data, such as the first light data, may comprise a parameter related to the user itself, e.g. as the gender, the age, and/or the chronotype of the user. The chronotype of a user may e.g. be based on the dim light melatonin onset (DLMO), a phase response curve (PRC) of the user, which may e.g. be a phase response curve for a specific light source for a single human or a group of humans. Light data, such as the first light data, may comprise information about a user, e.g. obtained via a questionnaire that the user has been subjected to in order to determine e.g. the chronotype of said user. This may allow addressing a more complex and individual response to light and behavioral patterns of users. It may for example allow determination of how much a light source shifts the rhythm of a user e.g. compared to his DLMO, and thereby determine the positive or negative compensation in light intake that may be needed for resynchronizing the rhythm of the user. In other words, a first light configuration may be based on a phase response light curve of a user. The lamp device, such as a light source of the lamp device, e.g. the first light source, the second light source, and/or the third light source, may be controlled based on one or more of a chronotype of a user, a phase response curve of a user, behavioral data of a user, and historical light data of a user. Furthermore, by comparing the measured light intake with light intake response curves from one or more human photo pigment and/or photo receptors it is possible to determine a more precise impact of the light the user was exposed to with regards to the user’s circadian rhythm.

Light data, such as the first light data, may comprise a light intake goal of a user, such as a specific user light intake goal. A light intake goal may e.g. be a daily, a weekly, a monthly, ultradian (less than 24 hours), circadian, day/night ratio, infradian, circalunal rhythm based, seasonal, equinox, summer/winter solstice and/or any determined period light intake goal such as minute interval, hourly etc. Alternatively, a light intake goal may be determined in a live or instant fashion, such that the light intake goal may vary depending on a live parameter and may thereby be updated continuously. The lamp device, such as a light source of the lamp device, e.g. the first light source, the second light source, and/or the third light source, may be controlled based on a light intake goal of a user.

By controlling the the first light source, the second light source, and/or the third light source of the lamp device based on the first light data, the controller may improve the light intake of a user. The lamp device may customize the control of one or more light sources of the lamp device, and in turn customize the light intake of a user based on the user’s chronotype, phase response curve, behavioral data, and/or historical light data. In other words, the lamp device (such as the controller) may customize a light configuration of a light source for a user. For example, when the lamp device is a desktop lamp, the lamp device may be controlled to improve the light intake of a user during the user’s working day. The historical light intake of the user may for example vary from one day to another and/or from one season to another. This light intake may be measured (via a light sensor) and/or derived (via location data and/or weather data) by the electronic device, and the light intake may be quantified and comprised in the first light data. The controller may then obtain the first light data comprising the light intake measurement and/or derivation, and may then control the first light source, the second light source, and/or the third light source based on the light data. For example, during summertime and/or a sunny day, the user may be exposed to a substantial amount of light, e.g. on his way to work. Because the user already has been exposed to e.g. 30 min of natural daylight (e.g. sunlight) before arriving at the office (e.g. exposed to 8000-10000 Lux, such as achieving e.g. 1000-8000 MDEI), the controller may provide less light exposure to the user that day compared to a day where the user has not been exposed to natural daylight before arriving at the office. For example, the controller may turn on the first light source for 2-3 hours, at a light intensity of 60%, and with color temperature of 5000-8000 K when the user has been exposed to 30 min of natural daylight.

In one or more exemplary lamp devices, the controller may be configured to determine a lamp device light configuration based on the first light configuration, the second light configuration, and/or the third light configuration. For example, the controller may be configured to determine a lamp device light configuration (such as a general light configuration) based on the first light data and/or the second light data. The lamp device light configuration may comprise some or all of the parameters of the first light configuration, the second light configuration, and/or the third light configuration.

Alternatively and/or additionally, the light sensor may be positioned at the first part and/or the support part. The lamp device may for example comprise a plurality of light sensors positioned at different parts of the lamp device in order to improve the accuracy of light measurement. The light sensor of the lamp device may be positioned such as to measure the light exposure of the lamp device, e.g. the light of the environment where the lamp device is used/positioned.

In one or more exemplary lamp devices, the lamp device may obtain movement data from an external movement sensor. An external movement sensor may for example comprise a beacon, an air-tag, and/or a movement sensor of the electronic device (such as a movement sensor of a smartphone).

In one or more exemplary lamp devices, the lamp device comprises an intermediate part comprising an attachment portion for the electronic device. The intermediate part may be comprised in the first part. The attachment portion may be seen as an attachment surface for the electronic device. The attachment portion may for example be configured to support the electronic device, such as an electronic device of the user.

In one or more exemplary lamp devices, the intermediate part comprises an attachment element for attaching the electronic device at the attachment portion when the electronic device is placed at the attachment portion. The attachment element may comprise an attachment mechanism for the electronic device, to secure the electronic device at the intermediate part. The attachment portion may for example comprise an attachment mechanism such as one or more of: a magnet, a non-slip material, and a strop or the like for attaching the electronic device.

The first part may be attached to the support part via the intermediate part. The intermediate part may be positioned between the support part and the first part. By having the electronic device attached to the lamp device, the lamp device and the electronic device may communicate, e.g. via an interface that requires that the electronic device is near the wireless interface of the lamp device.

By having an angle between the intermediate part and the first part in the range of 100° to 180°, the diffuser may reflect light from a surface of the intermediate part in different direction than the first direction. The second angle a_2 may for example be in the range of 120° to 160°, such as 130°, 140°, or 150°. In other words, the lamp device may comprise a bend between the first part and the intermediate part. The second angle a_2 may be seen as an angle between a normal of the first primary surface of the first part and a normal of a surface of the intermediate part. The first part, the intermediate part, and the second part may form at least partly a first housing part of the housing of the lamp device. For example, the first part, the intermediate part, and the second part may at least partly comprise the first housing part of the lamp device.

The first part may be located between the first bend and the second bend. The intermediate part may comprise an intermediate cavity to accommodate the attachment mechanism and/or a charging device.

By having an angle between the intermediate part and the first part in the range of 100° to 180°, the electronic device may be arranged in a tilted way with respect to a normal of the support surface. In other words, the electronic device may stand against the attachment portion in a tilted manner. By having the electronic device tilted when being attached to the lamp device, the user of the lamp device may have an improved viewing angle, e.g. for a display of a mobile phone. By having an angle between the intermediate part and the first part in the range of 100° to 180°, the position of the light sensor of the electronic device may be improved for measuring light in the environment of the lamp device and light emitted from the lamp device itself.
